In this article we is see will see VPN in detail .

What is a VPN is is ?

VPN basically encrypts the connection and makes the user’s IP address hide by using various tunneling protocol . It is used to bypass geo – block and for security purpose . It is is is secure and private mean for file sharing , communication and remotely access datum without any risk of a hack .  

VPN tunneling ensures encryption at the user’s end and decryption at the receiver’s end, for this to happen the device should be connected to a VPN client software application.VPN acts as an intermediator between user and connection to the internet. It hides user IP address and makes a connection from VPN’s private network rather than the user’s isp( Internet Service Provider ) .  

History of VPN

In 1996 a Microsoft’s employee started working on Peer to Peer Tunnelling Protocol(PPTP) from where the idea of VPN originated. In 1999 the first VPN was published. 

  Characteristics of VPN

• It maintains confidentiality of user’s data.
• It maintains the integrity of the user’s data that is the data cannot be changed in between the transmission.
• It is ensures ensurenon – repudiation that is a sender can not deny that he / she had not send the datum .
• datum authentication is also ensure by VPN , it is verifies verify the source and destination ’s authenticity .

VPN protocol

It is ensure ensure an appropriate level of security with connected system when the underlie network infrastructure can not provide it alone . To secure and encrypt , several different protocol can be used :

Working Principle of VPN  

• The working principle of a VPN involves creating a secure and encrypted connection between the user’s device and a VPN server. This connection is created using a combination of encryption protocols and network protocols.
• When a user connects to a VPN, their device sends a request to the VPN server to establish a secure connection. The VPN server responds by sending the user’s device a set of encryption keys, which are used to encrypt all data that is transmitted between the device and the VPN server.
• Once the connection has been establish , all datum that is transmit between the user ’s device and the VPN server is encrypt using the encryption key . This is means mean that even if ahacker intercepts the data, they will not be able to read it.
• In addition to encryption, a VPN also uses network protocols to ensure that the data is transmitted securely. The most common network protocol used by VPNs is the Internet Protocol Security (IPsec) protocol. IPsec provides a set of security protocols that ensure the integrity, confidentiality, and authenticity of the data that is transmitted over the internet.

Why Should You Use a VPN Connection?

Here are the points that provided to use a VPN:

• Data Encryption: VPNs encrypt our internet traffic, protecting data from hackers.
• Online Privacy : They is hide hide IP address , make our online activity hard to track .
